Solution - Simplification or other simple results

Step  1  :

 1.1     10 = 2•5

(10)² = (2•5)² = 2² • 5²

Equation at the end of step  1  :

  (9 • (103)) -  (5 • (22•52))

Step  2  :

Raising to a Power :

 2.1    5¹  multiplied by  5²   = 5^{(1 + 2)} = 5³

Equation at the end of step  2  :

  (9 • (103)) -  (53•22)

Step  3  :

 3.1     10 = 2•5

(10)³ = (2•5)³ = 2³ • 5³

Equation at the end of step  3  :

  (9 • (23•53)) -  (53•22)

Step  4  :
